I am completing all the steps. After i press the "unlock" icon, it says success. However when i put it my t-mobile SIM, it either says invalid SIM. (Or the "E" icon is their for EDGE however, it does not show the "Carrier" logo in settings. Nor the "EDGE" logo in networks. Also by the "E" i have no logo. Any suggestions? i have done every step over and over again around 5 times now.

Thanks for the guide. I have used it twice already and it worked perfectly, but now I'm having problems.

I get all the way to the step where you have to install the community sources, dns tools, bsd subsystem and open ssh. The first 2 times I did this it all went fine but now when I try on a new phone it doesn't have the dns tools.
I had to update the installer to the latest version so I think it's because of that and I tried installing bsd subsystem and just leaving out the dns tools altogether but it won't install, I get an error saying "Error Timed Out".
